Abstract:In order to solve the low mining height and small mining space in thin seam,an unfavorable personal operation and walking,low efficiency,high labor intensity and other difficulties,in combination with the fully-mechanized coal mining practices in thin seam for many years,the paper systematically analyzed major factors to restrict the low production of a single mining face.The existed problems of the hy-draulic powered support structure,hydraulic supply system and others were improved and perfected.The automatic control and the video monitoring and control technology were applied to improve the automation level of the coal mining equipment.The mining results of the coal mining face in thin seam of Guoerzhuang Mine showed that a single pass cutting coal time was reduced from one hour to 40 min,a circula-tion number per shift was increased by 1/ 3,a single face production was increased from 60 000 t to over 80 000 t and the fully-mechanized automatic,safety and high efficient mining was realized.Finally,according to the problems existed in the site application process of the au-tomatic equipment,the prospects on the three machine integrated effect,the automatic system promotion and application and the key re-search orientation were conducted.
